I was thirsty for Java (as usual) on a flight and asked for a cup of hot water which the stewardess supplied with a curious look. I lifted a packet of my coffee (Javita) when she left and relaxed to a refreshing cup. Many types are available on the shelf in individual packs but buyer beware that it may not rate….

But you could ditch the scale, pre-weigh your beans, and use an Aeropress with volume markers while travelling Only downside is when you find yourself in a hotel with only flimsy plastic cups.. then you’re doomed.
